What is the function of a food thermometer?

The function of a food thermometer is to accurately measure the internal temperature of food to ensure it is cooked safely. This is crucial in food safety practices, as different types of food need to reach specific temperatures to kill harmful bacteria and pathogens that can cause foodborne illnesses. For example, poultry should be cooked to an internal temperature of 165°F (74°C), while ground meats require a minimum of 160°F (71°C). Using a thermometer not only assures that the food is safe to eat but also helps in achieving the desired doneness and quality of the food.

The other options do not capture the primary role of a food thermometer. The weight of food can be measured with a scale, freshness can be assessed through visual and sensory inspections, and flavor cannot be quantified using a thermometer. Therefore, a food thermometer serves the important and specific purpose of monitoring temperature, essential for safe food handling and preparation.
